大家好，好长时间不见了！！一个特急的问题，再线等，请帮忙
描述：
我在GridView中的第一列中添加了checkbox,要实现，当点选择某列的checkbox后，要捕捉到checkbox的状态，并取得相应行的其它数据信息。
问题：
但是，我在button事件中总是捕捉不到checkbox 的选中状态，能找见gridview中的checkbox，但是他的状态总是为false.
代码：.aspx:
<asp:GridView ID= "GridView1 " runat= "server " Width= "534px " AutoGenerateColumns= "False " OnSelectedIndexChanged= "GridView1_SelectedIndexChanged ">
<Columns>
<asp:TemplateField>
<EditItemTemplate>
<asp:CheckBox ID= "CheckBox1 " runat= "server " />
</EditItemTemplate>
<ItemTemplate>
<asp:CheckBox ID= "CheckBox1 " runat= "server " />
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField= "roleInfoID " HeaderText= "角色代码 " />
<asp:BoundField DataField= "roleInfoName " HeaderText= "角色名称 " />
</Columns>
</asp:GridView>
<asp:CheckBox ID= "CheckBox2 " runat= "server " OnCheckedChanged= "CheckBox2_CheckedChanged "
Text= "全选 " />
<asp:Button ID= "Button1 " runat= "server " Text= "提交 " OnClick= "Button1_Click " Width= "58px "/>
</td> </tr>
代码.aspx.cs：
protected void Button1_Click(object sender, EventArgs e)
{
int k = 0;
string Message = " ";
string url = this.PageRoot + "UserInformation/RoleToUser.aspx ";
SysUserRoleCVO sysUserRoleCVO = new SysUserRoleCVO();
CheckBox cbox;
// 进行用户和角色的关联string nc=this.Request.Form.Get( "CheckBox1 ");
for ( k = 0; k < GridView1.Rows.Count; k++)
{
cbox = (CheckBox)GridView1.Rows[k].FindControl( "CheckBox1 ");
//((CheckBox)GridView1.Rows[i].FindControl( "CheckBox1 ")).Checked
if (cbox.Checked == true)
{
sysUserRoleCVO.RoleInfoID= int.Parse (((TextBox)(GridView1.Rows[k].Cells[1].Controls[0])).Text.ToString().Trim());
sysUserRoleCVO.UserCode =sysUserInfoCVO[this.DropDownList1 .SelectedIndex].UserCode ;
Message += roleToUser.Add(sysUserRoleCVO);
}
}
foreach (GridViewRow row in GridView1.Rows)
{
CheckBox cb = (CheckBox)row.FindControl( "CheckBox1 ");
string id1 = this.GridView1.DataKeys[row.RowIndex].Values[1].ToString();
if (cb.Checked == true)
{
string id = this.GridView1.DataKeys[row.RowIndex].Values[1].ToString();
}
}
Response.Redirect(this.PageRoot + "common/TimeoutErr.aspx?Message= " + Message + "&url= " + url);
}
定义checkbox：CheckBox cbox;
for循环：
for ( k = 0; k < GridView1.Rows.Count; k++)
{
cbox = (CheckBox)GridView1.Rows[k].FindControl( "CheckBox1 ");
//((CheckBox)GridView1.Rows[i].FindControl( "CheckBox1 ")).Checked
if (cbox.Checked == true)
{
其中：cbox.Checked 纵使显示为false
谢谢，急等！！
[解决办法]
当点选择某列的checkbox后，要捕捉到checkbox的状态，并取得相应行的其它数据信息。
以前做过的例程
private void DataGrid1_ItemCreated(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
if((e.Item.ItemType==ListItemType.Item)|| e.Item.ItemType==ListItemType.AlternatingItem))
{
CheckBox cb_Department =(CheckBox)e.Item.FindControl( "cb_Department ");
cb_Department.AutoPostBack=true;
cb_Department.CheckedChanged+=new EventHandler(cb_Department_CheckedChanged);
}
}

我把我的代码贴出来，供你参考：
